Janet Raloff

Editor, Digital, Science News Explores

Editor Janet Raloff has been a part of the Science News Media Group since 1977. While a staff writer at Science News, she covered the environment, toxicology, energy, science policy, agriculture and nutrition. She was among the first to give national visibility to such issues as electromagnetic pulse weaponry and hormone-mimicking pollutants, and was the first anywhere to report on the widespread tainting of streams and groundwater sources with pharmaceuticals. A founding board member of the Society of Environmental Journalists, her writing has won awards from groups including the National Association of Science Writers. In July 2007, while still writing for Science News, Janet took over Science News Explores (then known as Science News for Kids) as a part-time responsibility. Over the next six years, she expanded the magazine's depth, breadth and publication cycle. Since 2013, she also oversaw an expansion of its staffing from three part-timers to a full-time staff of four and a freelance staff of some 35 other writers and editors. Before joining Science News, Janet was managing editor of Energy Research Reports (outside Boston), a staff writer at Chemistry (an American Chemical Society magazine) and a writer/editor for Chicago's Adler Planetarium. Initially an astronomy major, she earned undergraduate and graduate degrees from the Medill School of Journalism at Northwestern University (with an elective major in physics).

    Walnuts slow prostate cancer growth

    A new study suggests that mice with prostate tumors should say “nuts to cancer.” Paul Davis of the University of California, Davis, hopes follow-up data by his team and others will one day justify men saying the same.

    Smokin’ entrees: Charcoal grilling tops the list

    At the American Chemical Society meeting, earlier this week, I stayed at a hotel that fronted onto the kitchen door of a Burger King. This explained the source of the beefy scent that perfumed the air from mid-morning on – the restaurant’s exhaust of smoke and meat-derived aerosols. A study presented at the meeting confirmed what my nose observed: that commercial grilling can release relatively huge amounts of pollutants.

  3. Chemistry

    The skinny on indoor ozone

    Indoor concentrations of ozone tend to be far lower than those outside, largely because much gets destroyed as molecules of the respiratory irritant collide with surfaces and undergo transformative chemical reactions. New research identifies a hitherto ignored surface that apparently plays a major role in quashing indoor ozone: It’s human skin. And while removing ozone from indoor air should be good, what takes its place may not be, data indicate.

  4. Chemistry

    BPA found beached and at sea

    Food chemists have been showing for years that bisphenol A, an estrogen-mimicking building block of polycarbonate plastics and food-can coatings, can leach into food and drinks. But other materials contain BPA – and leach it – such as certain resins used in nautical paint. And Katsuhiko Saido suspects those paints explain the high concentrations of BPA that he’s just found in beach sand and coastal seawater around the world.

    Athlete’s foot therapy tapped to treat bat-killing fungus

    Over the past four years, a mysterious white-nose fungus has struck hibernating North American bats. Populations in affected caves and mines can experience death rates of more than 80 percent over a winter. In desperation, an informal interagency task force of scientists from state and federal agencies has just launched an experimental program to fight the plague. Their weapon: a drug ordinarily used to treat athlete’s foot.

    Cool roof coating: Mechanism kept under wraps

    The American Chemical Society held a news briefing March 21 to feature a new energy-saving technology. It’s an ostensibly “smart” coating for roofing materials that knows when to reflect heat, like in summer time, and when to instead let the sun’s rays help heat a structure.

    Bees face ‘unprecedented’ pesticide exposures at home and afield

    Honey bees are being hammered by some mysterious environmental plaque that has a name — colony collapse disorder – but no established cause. A two-year study now provides evidence indicting one likely group of suspects: pesticides. It found “unprecedented levels” of mite-killing chemicals and crop pesticides in hives across the United States and parts of Canada.

  8. Health & Medicine

    Vitamin D is a flu fighter

    Japanese researchers offer tangible support for that idea that vitamin D deficiency might render people vulnerable to infections. Supplementing school children with the vitamin, they showed, dramatically cut their incidence of seasonal flu.

    Don’t know much about…

    A measure of U.S. science literacy has increased - to 28%

    Cats attracted to ADHD drug, a feline poison

    Since 2004, drugs designed for use by people have been the leading source of poisonings among companion animals, according to the national Animal Poison Control Center in Urbana, Ill. And among cats, Adderall – a combination of mixed amphetamine salts used to treat attention deficit hyperactivity disorder – has quickly risen to become one of the most common and dangerous of these pharmaceutical threats.

  11. Health & Medicine

    For a lucky few, ‘dioxins’ might be heart healthy

    Dioxins and their kin are notorious poisons. They work by turning on what many biologists had long assumed was a vestigial receptor with no natural beneficial role. But it now appears that in a small proportion of people, this receptor may confer heart benefits.

  12. Climate

    National academies to review IPCC procedures

    Global science organizations asked to help evaluate processes that produced 2007 climate report.
